I have been closely observing my wind speed gauge over the last few days during various windy periods. I did notice periods where the red gust 'wedge' would disappear for a short period. I observed several occasions where the indicated wind speed went higher than the existing 10 minute gust value, on all occasions the ten minute gust value was immediately increased and the red gust wedge similarly increased in size immediately to match the indicated wind speed. > It is my understanding that the value of "wgust" is supposed to be the > speed of the highest gust over the last ten-minutes.

The issue in this case was the method in which the ten minute wind gust value was derived from the ten minute wind speed list. This has been fixed in v0.2.9. I have no solution for the gusts you observed that did not update the ten minute gust value. I have not been able to replicate this issue and I have reviewed the code and am confident it is correctly capturing windSpeed data and calculating 10 minute gust values. I suggest you upgrade to v0.2.9 and see if the issue remains, if so we need to determine the conditions under which the issue occurs. If this is not possible visually then I have some wind speed debug code that will dump the windSpeed history list and other key values to log and we will need to wade through the figures to determine the issue. I did go to your previously posted link to try to observe the issues you describe myself but the link now gives me a 403 Forbidden error.
